LIGHT RAIL SLEEPERS FOR URBAN TRANSPORTATION

​

The manufacturing-process of prestressed concrete sleepers for urban transportation happens similar to the production of sleepers for main line tracks. The diffrence consists of building-height and mounting points. Pre-stressed concrete sleepers for urban transportation stand out in Terms of flexibility in reference to the assembling of security tracks, and also because of the direct anchoring of power supply. The sleepers are equipped with grooves for signaling cables, enabling the fit of the signal-cable similar to the ground.

​

Special requirements demand specific solutions . For that reason different types of sleepers are constructed and used for urban transportation.

​

At all types the rails are mounted with ribbed base plates . By underlying plastic-pads,the concrete body is seperated from the base plate. Moreover all sleepers can be equipped wit an undersleeper-pad which enables the protection of the ballestbed and provides a more smoother run of the rolling stock.
